The NFL preseason is heating up with unexpected injuries and surprising moves. The New York Giants' practice was disrupted when wide receiver Calvin Austin was carted off the field with a potentially serious knee injury. Austin, a key player for the Giants, was injured during a routine drill, bringing practice to a halt. The severity of the injury is not yet clear, but the incident has raised concerns about the team's depth at the wide receiver position.

The Washington Commanders have been active in reshaping their roster. The team signed a former DC Defenders pass rusher and released veteran safety Will Harris.
